To @ZZ whom t may concern Be it known that l, ALBERT H. PILLS- nUnr, a citizen of the United States, residing at Lyndon Station, in the county of Juneau and State of 1Wisconsin, have invented certain new and useful Improvements in Obstetrical Instruments; and l do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to improvements in obstetrical instruments for use in connection with the delivering of horses, cows and like animals.

When a calf or colt has been delivered the parent animal suers to such an extent that the womb or what is commonly called the bed is thrown out of place and it is the object of my invention to pro-vide simple and effective means whereby the womb may be engaged and held in proper position until the animal has regained sufficient strength to retain the organ in place.

The principal advantage of my invention is that it eliminates necessity of sewing thel dislocated organ in position.

Another and more specific object is to provide an instrument of the character described which comprises an inflatable pad of such shape as to prevent injury to the organ and to securely hold it in proper position.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following` specification and then more particularly pointed out in the claim.

With reference to the drawings, wherein l: have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figurel is a plan view of my improved device showing it broken away and in section, and Fig. 2 is a side elevation.

Referring to the drawings by characters of reference, 1 designates preferably, a rubber pad that is substantially heart shaped and comparatively flat. `This pad l is arranged to be inflated after being placed in position as will be later described and has the apex portion thereof provided with Specification of Letters Patent.

an attaching tube 2 carried thereby and to which is secured an inflating pipe or hose 3. The pipe 3 has the end which receives valve 6 is carried within the pipe 5 intermediate the ends thereof and is arranged to permit the air to be forced into the pad l. The outer end of the pipe 5 is internally screw threaded as at 7 so that it may be connected with a suitable hose from a source of air supply. To deflate the pad l the tube 3 is removed from the connecting member 2. rlhe large end of the pad l is concaved as at 8 so as to conform to the curvaw ture of the womb or bed 7 which it engages and eliminates possibility of injury thereto.

In use, the pad l is 4placed in deiated con dition, within the vagina after the calf or colt has been delivered, so as to engage and hold thd dislocated womb or bed in place until the parent animal has regained sufhcient strength to retain the organ in position. vThe pad is inflated after being forced into proper position so as to hold the dislocated organ securely in place.

ln practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, l desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention, as claimed. l p

l/Vhat is claimed is An obstetrical instrument comprising a substantially heart-shaped inflatable pad, a tube extending through'the apex end of the pad and having its inner end provided with a flange curved to conform to the configuration of the inner wall of the apex portion of the pad, the outer end of the tube being spaced from the pad, a pipe having one end detachably engaging over the outer end of the tube, the said end of the pipe having a substantially conoavo-convex iiange thereon, In testimony whereof I aiix my signature the conceived surface of Whlch 1s adapted to in presence of two Witnesses. engage and receive the apex end of the pad,
